Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer or a
“CHECK GASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in ”Un-
derstanding Your Instrument Panel” for further informa-
tion. Tighten the gas cap until aclickingsound is heard.
This is an indication that the gas cap is properly tight-
ened.
Press the odometer reset button to turn the message off.
If the problem persists, the message will appear the next
time the vehicle is started. This might indicate a damaged
cap. If the problem is detected twice in a row, the system
will turn on the MIL. Resolving the problem will turn the
MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.

MAINTAINING YOUR VEHICLE 593

Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part
of a normal bulb check.
4. Approximately 15 seconds later, one of two things will
happen:
•
The MIL will flash for about 10 seconds and then return
to being fully illuminated until you turn OFF the igni-
tion or start the engine. This means that your vehicle’s
OBD II system isnot readyand you shouldnotproceed
to the I/M station.
•The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
isreadyand you can proceed to the I/M station.
If your OBD II system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.

Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut OFF or before starting the
engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain the
oil level between the MIN and MAX markings on the
dipstick. Adding one quart of oil when the reading is at the
MIN mark will result in a MAX reading on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration, or
loss of oil pressure. This could damage your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever occurs first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Chrysler Material Standard MS-6395.

Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the engine
compartment and should be checked at regular intervals.
Fill the reservoir with windshield washer solvent (not
radiator antifreeze) and operate the system for a few
seconds to flush out any residual water.
The washer fluid reservoir will hold a full gallon of fluid
when the Low Washer Fluid Light illuminates.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.After the engine has warmed, operate the defroster for a
few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. MOPAR® All
Weather Windshield Washer Solution or equivalent, used
with water as directed on the container, aids cleaning
action, reduces the freezing point to avoid line clogging,
and is not harmful to paint or trim.
Cooling System
WARNING!
•When working near the radiator cooling fan,
disconnect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at anytime the ignition
switch is in the ON position.

608 MAINTAINING YOUR VEHICLE

WARNING!(Continued)
•You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had
time to cool. Never try to open a cooling system
pressure cap when the radiator is hot.
Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty, the
system should be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS-12106) only by an
authorized dealer. Check the front of the A/C condenserfor any accumulation of bugs, leaves, etc. If dirty, clean by
gently spraying water from a garden hose vertically
down the face of the condenser.
Check the coolant recovery bottle tubing for brittle rubber,
cracking , tears, cuts and tightness of the connection at the
bottle and radiator. Inspect the entire system for leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.

Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based
engine coolant in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine OFF and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle.The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
engine coolant (antifreeze) freeze point or replacing cool-
ant. Advise your service attendant of this. As long as the
engine operating temperature is satisfactory, the coolant
bottle need only be checked once a month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, only OAT coolant that meets the
requirements of Chrysler Material Standard MS-12106
should be added to the coolant bottle. Do not overfill.
Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.7
MAINTAINING YOUR VEHICLE 613

If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant expansion bottle.
•
Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
•
Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to MS-12106)
and distilled water for proper corrosion protection of
your engine which contains aluminum components.
•Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
•
Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
614 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other thanyour authorized dealer, the message can be reset by refer-
ring to the steps described under “Electronic Vehicle Infor-
mation Center (EVIC)/Oil Change Required” in “Under-
standing Your Instrument Panel” for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
•Check engine oil level
•Check windshield washer fluid level
•Check the tire inflation pressures and look for unusual
wear or damage
•
Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission as
needed
•Check function of all interior and exterior lights
